v1.817.0 mineru-4.0.6-released
Gerstep/cybosSep 22, 2026 → Sep 22, 20260 days between releases
What's New
Adds an EPUB viewer to the WebUI and fixes PDF export crashes; notes do not reference the older release's changes.
Breaking Changes
- Minimum docvortex version is now 0.4.22, so environments pinned to an older docvortex must upgrade it before installing this release.
New Features
- EPUB online preview in the WebUI with section navigation and improved metadata display.
Improvements
- EPUB static assets are served through a browser proxy rather than loaded directly.
- Dependency floor for docvortex raised to 0.4.22.
Bug Fixes
- Fixed a regression where PDF text blocks lacking line information were dropped entirely during normalization, now handled with a bbox fallback.
- Fixed a crash when exporting PDFs containing CJK paragraphs with inline formulas, caused by a reportlab CJK line-breaking defect, and added a regression test.
Upgrade Notes
The two release note sets describe unrelated change sets, so treat this delta conservatively: only the EPUB viewer, the two PDF fixes, and the docvortex floor are evidenced. Verify your docvortex pin is at least 0.4.22 before rolling out, and re-test PDF export paths that involve CJK text or inline formulas. No config or migration steps are mentioned.
